螺桿泵選用時(shí)如果考慮不周，將會(huì)給以后的使用、管理、維修帶來(lái)巨大的麻煩，因此客戶(hù)在選擇螺桿泵時(shí)必須選用一臺(tái)按生產(chǎn)實(shí)際需要，合理可靠的螺桿泵，這樣既能保證生產(chǎn)順利進(jìn)行，又可降低修理成本。同時(shí)在輸送污水時(shí)還要注意合理使用我妮螺桿泵，現(xiàn)將我們?cè)趹?yīng)用螺桿泵的一些體會(huì)介紹如下：確保雜物不進(jìn)入泵體 </p> <p> 濕污泥中混入的固體雜物會(huì)對(duì)單螺桿泵的橡膠材質(zhì)定子造成損壞，所以必須確保雜物不進(jìn)入單螺桿泵泵的腔體，建議可以在泵前加裝粉碎機(jī)，或者安裝格柵裝置或?yàn)V網(wǎng)以便阻擋雜物進(jìn)入螺桿泵，對(duì)于格柵應(yīng)及時(shí)清撈以免造成堵塞。計(jì)量泵保持恒定的出口壓力 </p> <p> 單螺桿泵是一種容積式回轉(zhuǎn)泵，當(dāng)出口端受阻以后，壓力會(huì)逐漸升高，甚至將會(huì)超過(guò)預(yù)定的壓力值，增加電機(jī)負(fù)荷，同時(shí)傳動(dòng)機(jī)械相關(guān)零件的負(fù)載也會(huì)超出設(shè)計(jì)值，嚴(yán)重時(shí)會(huì)發(fā)生電機(jī)燒毀、傳動(dòng)零件斷裂。為了避免螺桿泵損壞，一般會(huì)在螺桿泵出口處安裝旁通溢流閥，用以穩(wěn)定出口壓力，保持泵的正常運(yùn)轉(zhuǎn)。離心泵

螺桿泵輸送化工介質(zhì)選型指南，談起泵設(shè)備機(jī)械制造領(lǐng)域，螺桿泵往往是繞不開(kāi)的話(huà)題。螺桿泵是一種新型輸送機(jī)械，采用壓縮空氣或電機(jī)為動(dòng)力源，螺桿泵它是由膜片往復(fù)變形造成容積變化的容積泵。螺桿泵質(zhì)量可靠，使用壽命長(zhǎng)，噪音低，振動(dòng)小，不崩潰，工作精細(xì)等六大優(yōu)點(diǎn)，既可泵送常規(guī)流動(dòng)介質(zhì)，又可用于輸送一些不易流動(dòng)的介質(zhì)，具有自吸泵、潛水泵、屏蔽泵、泥漿泵等雜質(zhì)輸送機(jī)械的優(yōu)點(diǎn)。螺桿泵根據(jù)不同液體介質(zhì)分別采用丁晴橡膠、氯丁橡膠、氟橡膠、聚四氟乙烯。以滿(mǎn)足不同用戶(hù)的需要。氣動(dòng)螺桿泵、電動(dòng)螺桿泵廣泛應(yīng)用于石油、化工、電子、陶瓷、紡織、油漆、制藥機(jī)械等行業(yè)。螺桿泵重點(diǎn)打造以螺桿泵智造為特征的QBK型氣動(dòng)螺桿泵、QBY型氣動(dòng)螺桿泵、DBY型電動(dòng)螺桿泵、DP型微型螺桿泵產(chǎn)品，注重螺桿泵設(shè)備制造領(lǐng)域的研究與開(kāi)發(fā)，為客戶(hù)提供完整解決方案，并由雄厚的技術(shù)實(shí)力與創(chuàng)新的商業(yè)模式提供輔助和支撐。在客戶(hù)使用過(guò)程中遇到任何問(wèn)題有專(zhuān)業(yè)的技術(shù)團(tuán)隊(duì)和售后服務(wù)團(tuán)隊(duì)為客戶(hù)提供個(gè)性化的產(chǎn)品選擇和質(zhì)量的產(chǎn)品服務(wù)，下面貼出部分**內(nèi)容供參考。壓力高而均勻，流量均勻，轉(zhuǎn)速高，能與原動(dòng)機(jī)直聯(lián)。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="惠州官方螺桿泵,螺桿泵" src="http://tyunfile.71360.com/UploadFile/qunxun/637211876905917968/581422.jpg"></div><p> 二、螺桿泵的轉(zhuǎn)速選用 </p> <p> <br /> </p> <p> 螺桿泵的流量與轉(zhuǎn)速成線性關(guān)系，相對(duì)于低轉(zhuǎn)速的螺桿泵，高轉(zhuǎn)速的螺桿泵雖然能增加了流量和揚(yáng)程，但功率明顯增大，高轉(zhuǎn)速加速了轉(zhuǎn)子與定子間的磨耗，必定使螺桿泵過(guò)早失效，而且高轉(zhuǎn)速螺桿泵的定轉(zhuǎn)子長(zhǎng)度很短，極易磨損，因而縮短了螺桿泵的使用壽命。 </p> <p> <br /> </p> <p> 三、確保雜物不進(jìn)入泵體 </p> <p> <br /> </p> <p> 濕污泥中混入的固體雜物會(huì)對(duì)螺桿泵的橡膠材質(zhì)定子造成損壞，所以確保雜物不進(jìn)入泵的腔體是很重要的，很多污水廠在泵前加裝了粉碎機(jī)，也有的安裝格柵裝置或?yàn)V網(wǎng)，阻擋雜物進(jìn)入螺桿泵，對(duì)于格柵應(yīng)及時(shí)清撈以免造成堵塞。 </p> <p> <br /> 能使泵長(zhǎng)期可靠工作的先決條件——應(yīng)使泵有良好的潤(rùn)滑。惠州官方螺桿泵</p><p style="text-indent:25px">由于螺桿是等速旋轉(zhuǎn)，所以液體出流流量也是均勻的?；葜莨俜铰輻U泵</p><p> 單雙螺桿泵和普通的工作原理及產(chǎn)品介紹，螺桿泵是利用螺桿的回轉(zhuǎn)來(lái)吸排液體的。螺桿為主動(dòng)螺桿，由原動(dòng)機(jī)帶動(dòng)回轉(zhuǎn)，兩邊的螺桿為從動(dòng)螺桿，隨主動(dòng)螺桿作反向旋轉(zhuǎn)。主、從動(dòng)螺桿的螺紋均為雙頭螺紋。由于各螺桿的相互嚙合以及螺桿與襯筒內(nèi)壁的緊密配合，在泵的吸入口和排出口之間，就會(huì)被分隔成一個(gè)或多個(gè)密封空間。隨著螺桿的轉(zhuǎn)動(dòng)和嚙合，這些密封空間在泵的吸入端不斷形成，將吸入室中的液體封入其中，并自吸入室沿螺桿軸向連續(xù)地推移至排出端，將封閉在各空間中的液體不斷排出，猶如一螺母在螺紋回轉(zhuǎn)時(shí)被不斷向前推進(jìn)的情形那樣，這就是螺桿泵的基本工作原理。 </p> <p> <br /> </p> <p> 螺桿泵有單螺桿泵、雙螺桿泵和三螺桿泵。 </p> <p> <br /> </p> <p> 螺桿泵的工作原理是：螺桿泵工作時(shí)，液體被吸入后就進(jìn)入螺紋與泵殼所圍的密封空間，當(dāng)主動(dòng)螺桿旋轉(zhuǎn)時(shí)，螺桿泵密封容積在螺牙的擠壓下提高螺桿泵壓力，并沿軸向移動(dòng)。由于螺桿是等速旋轉(zhuǎn)，所以液體出流流量也是均勻的。 </p> <p> <br /> </p> <p> 螺桿泵特點(diǎn)為：螺桿泵損失小，經(jīng)濟(jì)性能好。壓力高而均勻，流量均勻，轉(zhuǎn)速高，能與原動(dòng)機(jī)直聯(lián)。 </p> <p> <br /> </p> <p> 螺桿泵可以輸送潤(rùn)滑油，輸送燃油，輸送各種油類(lèi)及高分子聚合物，用于輸送黏稠液體。 </p> <p> <br /> 惠州官方螺桿泵</p><p
